I got a great deal on a 3COM 3CBLSG48 Baseline Switch (2948-SFP Plus), but am amazed at the amount of noise that it generates. Is it possible reduce the noise by replacing with a better fan or by shielding it from the rest of the room. This will be in an office environment that already has lots of computers and servers running (temperature is 65-75F most times), but the increased amount of noise that this brought to the room was astounding. "What?" seems to be the most used phrase now.
